About the Product:

Mapeguard UM 35 is a thin (1/8"), lightweight, flexible premium underlayment membrane with a rough surface and polypropylene fabric backing for preventing cracks. It provides superior flooring protection, crack isolation, and waterproofing for ceramic tile and stone installations. UM 35 compensates for differential movement in all directions, neutralizing tension between the substrate (concrete or wood structures) and tile. It is made from high-density polyethylene, which provides excellent flexibility, making it easy to apply on complex, uneven surfaces. Moreover, it offers some soundproofing properties, reducing noise transmission through the floors.
